Tendai, Kuda, and Rita are the sheltered children of the chief of security of a futuristic Zimbabwe.

There, they fall off the radar, and their father hires three detectives with special powers (Ear, Eye, and Arm) to find the lost children. The story jumps between narratives of Ear, Eye, and Arm and of the kids.

Every Christmas Eve, Maggie has the same dream. Santa is walking on the top of her grandfather's manor, when suddenly he slides off the end. But this year is different. This year, it's a nightmare in which he is pushed by something sinister. Awakened from her dream, she decides to go sledding - ending up in an accident that leads to meeting the handsome (but older) Henry. Henry has come with strange claims: that Maggie's grandfather, who is well known for writing the poem 'Twas the Night Before Christmas, had plagiarized his poem.

Penelope Jackson has had a hard life. Her earliest memories were living with her crack-addicted adopted mother - who died when she was 8. Scarred by horrible memories of that time, Penelope moved to live with her aunt JoAnne. Life for the next almost-10-years went pretty calmly. She wasn't popular in school, but she had her couple of good friends, and her loving aunt. But then everything changed. She found out that she'd been lied to her whole life. That she was a special immortal being called a "black five." She was the only one who could save the world from an evil tyrant.
